Band 6+: "The graph shows the demand for energy and the energy available from fossil fuels in Freedonia from 1985 to 2005. Write a report for a university lecturer describing the information shown below."

The graph presents the energy demand and available energy of fossil fuels in Freedonia from 1985 to 2005.

In a first decade, the energy demand experienced a gradual rise and reached the peak, with a figure was 650 billion megajoules. Then, it decreased swiftly, prior to 2000, to 250 billion megajoules. By 2005, there was the number remaining in the energy demand in Freedonia.

On the other hand, the opposite trend occurred in the energy available. A drop from 500 to 200 billion megajoules was suffered by the product of energy available in the first five years. After that, there was a period with no significant change in yield of energy available between 1990 and 1995. In the next decade, it increased steadily to 700 billion megajoules.

It was noteworthy that the energy available was over the energy demand from 1987 to 1999 and there were two opposite trends of energy available and the energy demand in this two decades in Freedonia.
